COFFEE-MAKING DEVICE Application led June 27, 1921.

To all whom t may concern:

Be it known that I, JOHN D. Houck, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Coffee-Making Devices, of which the following is a specification, reference being had therein to theaccoman in drawin p Tliisginventiois relates to coffee making machines and has for an object to provide an attachment for a receptacle, such as a coffee pot, urn or the like, which shall oo ntain the coffee in improved means while water is being poured therethrough to constitute of the coffee mass itself a filter .for filtering the 'decoction.

A further object of the invention isto rovide an attachment having a perforated bottom with means for supporting a fabric upon the bottom with a perforated top spaced above the fabric between which the ground coffee packs and swells to provide and produce a filter for removing all sediment from the decoction.

A further object of the invention is to provide a device of the class having improved features for convenience and rapidity of operation.

With these and other objects in view, the invention comprises certain novel parts, elements, units, combinations and arrangements as disclosed in the drawing together with mechanical equivalents thereof, as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a view of the device substantially in vertical diametrical section.

' Fig. 2 is a fragmentaryperspective view, one ofthe planes being taken substantially upon a diametrical section.

Fig. 3 is a top plan view of the device.

Fig. 4 is a diagrammatic view showing the improved manner of ,putting the parts together.`

Like characters of reference indicate corresponding parts throughout the several views.

The improved coffee making attachment which forms the subject matter of this application comprises a container 10, of a size and general shape to correspond to the parts with which 'it is to be associated, The container is provided with annular shoulders 11, 12 and 13, any one of which may be Specification of Letters Patent.

employed to support thedevice upon the edge of the p'ot or receptacle with which it is to be employed, although preferably the.

shoulder 12 will be employed for that purpose andthe device will referably be of such dimensions asto fit tfie pot, container or urn at that point.I

The bottom of the 4receptacle 10 is perforated, as indicated at 14, and upon the shoulder 11 a disk 15y is positioned. Between the perforated bottom 14 and the disk 15 a cloth or fabric 16 is employed, having its edges upturned and engaged between the periphery of the disk 15 and the shoulder 11. The cloth is `preferably of such dimension that it may be depressed to substantiall fill the chamber between the disk 15 and t e perforated bottom 14. The'disk l5 is provided with perforations 17 of such dimension that the ground coffee poured upon the disk 15 will pass throu h the perfoiations on to the fabric 16. he amount of ground coffee poured upon the disk 15 will depend upon the size of the container and the stren h of the decoction to be brewed, but will be an amount, of course, considerably in excess of that required to fill the chamber between the disk 15 and the Yperforated bottom 145. As water is poured 'upon the coffee restin upon the disk 15,

more of the ground co ee issluiced through the perforation 17 until the chamber below the disk 15 has been substantially filled, the fabric 16 yielding at its marginal edges to such filling and to conform f to the area of the chamber. The water thus poured through swells the ground coffee contained in the chamber, packino the coffee into a mass which forms an ideal filter for. the filtration of further fluid passed through. It is well known that in the use of such devices, boiling water is poured through the coffee and after passing through is drawn off and poured through again, sometimes an operation calling for the fpouring of liquid through several times. his gives the coffee a chance to swell, as stated, to form the filter for the decoction poured through the second and subsequent times.

It is evident that the swelling of the coffee below the disk 15 would have a tendency to raise the disk to prevent which lugs 18 are provided, preferably, though not necessarily, by striking up a part of the wall of the -container as indicated at Figs.
